First Claim
Patent Images
1. A network-initiated area event triggered positioning method for a roaming terminal in a mobile communication system, comprising:
- sending, by a first server, a session initiation message for initiating a trigger session to the roaming terminal;
receiving a session start message from the roaming terminal;
requesting area ids related to area event-triggered positioning from a second server and obtaining area ids;
sending a session response message including at least a trigger parameter to the roaming terminal;
receiving a positioning initiation message from the roaming terminal and transferring it to the second server;
receiving a calculated position value of the roaming terminal from the second server and transferring the received position value to the roaming terminal; and
providing the calculated position value received from the roaming terminal to an agent.

Abstract
A network-initiated area event triggered positioning method for a roaming terminal in a session-based position information system is disclosed. Network-initiation of area-based positioning of a roaming terminal is discriminated according to a proxy mode and a non-proxy mode, and area-based positioning for the roaming terminal is performed in various manners according to whether an SLP for performing the positioning procedure with respect to the discriminated modes is a V-SLP or an H-SLP.
